1. Some versions of Debian require you to install GnuPG:
   sudo apt-get install gpg
2. Add the Advanced Server Access repository key:
   curl -fsSL https://dist.scaleft.com/pki/scaleft_deb_key.asc | gpg --dearmor | sudo tee /usr/share/keyrings/scaleft-archive-keyring.gpg > /dev/null

3. Create a package resource list entry:

   OS Version	Command
   Ubuntu 20.04 only	printf "deb [arch=amd64 signed-by=/usr/share/keyrings/scaleft-archive-keyring.gpg] http://pkg.scaleft.com/deb focal main\ndeb [arch=amd64 signed-by=/usr/share/keyrings/scaleft-archive-keyring.gpg] http://pkg.scaleft.com/deb linux main" | sudo tee /etc/apt/sources.list.d/scaleft.list > /dev/null
   All other Ubuntu & Debian versions	printf "deb [arch=amd64 signed-by=/usr/share/keyrings/scaleft-archive-keyring.gpg] http://pkg.scaleft.com/deb linux main" | sudo tee /etc/apt/sources.list.d/scaleft.list > /dev/null
